Well, it wasn't until recently that GCC (4.3.x) started supporting -march=core2, and I don't think the DOSBox guys have started using that build yet (well, last official release was in August, so I doubt it). Besides, it's not multi-core aware yet, AFAICT, if ever (maybe too hard ??). Also, remember it's full emulation of a fast 486, not true virtualization.

If you can, you may have better luck with DOSEMU, which does have binary builds available on SourceForge.

"Unlike EMM386, EMS Magic does not use Virtual 8086 (V86) mode to enable hardware paging. Instead, data is copied to and from the page frame with XMS moves. Because hardware paging is not used, the page frame does not have to be aligned on a 4K/16K page boundary. Furthermore, because EMS Magic itself operates entirely in real mode, it does not cause problems when the CPU is already running in V86 or protected mode, as is the case with Windows."

"EMS Magic also tries to create a page frame in the UMA, but if there is no space, it will create the page frame in conventional memory."
